Really made it easy to balance airflow in my house. Highly recommended.

When we opened the box, the batteries were coroded and leaking. Apart from that the product seems OK.

Does the job, but probably a bit over priced

はじめ測定ファンのフロー方向がわからずにいましたが、どちらからでも風速が測定できふ、ファン部に内蔵された磁気センサーで方角も測定とロギングができるという本格的な風速計です。また、USB経由でPCと接続ができますが、記録データのほかにリアルタイムでデータ連携も可能です。簡易的な風速計は数多くでていますが、温度や方角、風速のmax/minに加えてロギングまでができる風速計がこんなリーズナブルな価格で買えるのはよい時代になったとつくづく思いました。簡易的な風速計では満足できない方にお勧めいたします。コスパがいいです。

There's a lot going on in this device and I made sure to read the manual and then some time to play with it before trying to take any real measurements. While it's not required that a person has a good understanding of what the tool is used for it sure helps. In the past, I've had the opportunity to use other anemometers but they were simplistic in their capabilities compared to this one.The reality is that this is more than just an anemometer, it really is more of a weather station, just as described.The display is easy to read and the manual which is written in real English provides a lot of detail. I found it simple to go through the manual and then operate or set the various features. I'm not going to list all of the things it is capable of, the seller has done a very good job of that.Operation:► Pop in the 4 included AAA batteries and the unit is ready to go.► It is a complicated device that's capable of some fairly complicated sensing.► The display is large and easy to read.► No tools are required to get it set up.► Materials used on both the meter and sensor handle allow for gripping even when wet.► Cable length between meter and sensor is 6 feet. So far I found this to be more than enough.► While not intuitive the buttons allow for various setup preferences.► While the disp0lay is backlit it's not so bright as to be distracting in a darkened area.► I like the auto power-off function if not used for a period of time.► I found the temperature to be with 0.1 degreed C as compared to other electronic thermometers.► Accuracy for humidity measurements is within 0.1%► While the meter has a 1/4 threaded receptacle for use with things like tripods the sensor does not. This means that the sensor must be handheld which can lead to some variation due to a little movement. If it instead of the meter could be tripod mounted accuracy would be higher.I had been using a small handheld anemometer for tweaking the ducting in my home and it did help me to make some much-needed changes so that every room was getting what I thought was the same amount of air based simply on wind speed. What I discovered once I used this meter is that I was only measuring the air velocity but not the volume of air that was passing through any one particular duct. Once this was taken into account, plus I was getting greater accuracy, and other tweaks were made (ducting replaced with a larger diameter as needed) I now have a ducting system that provides equal amounts of cooling or heating air volumes to each room.While it's not something that I particularly need for my purposes, I do like the idea of being able to log data and then connecting to a PC so the data can be downloaded and mined. I went to the URL indicated in the manual, downloaded the software, installed it without a glitch, and in a couple of minutes I was connected. I see where other reviewers had problems with the software, all I can say is that mine installed and worked the first time without issue.An interesting item, there is a compass but it's built into the sensor head, not the meter body. It took a little playing around to get it figured out since it doesn't work as a standard electronic compass. Basically the sensor head needs to be held straight up, then as you turn the head the reading indicates in which direction the head is pointed. Once sorted it is simple to use.It's not a hugely expensive tool but with the functionality, it has the price is decent when compared to the other anemometers I've used.On the downside:► While it can show both temperatures (C or F) and temperature and humidity it cant show both at the same time.

Muy buen producto, eficiente.

“Weather Station” led me down an inaccurate path. I expected that we would set this up in more or less a stationary location. Our interest in it is derived from our hillside location in the Sierra foothills, between towns, where we seldom get accurate weather forecasting of wind velocity, temperature or humidity.. We get destructive winds which could cause problems because we are a lavender farm getting ready to plant our first acre. The experimental plot we planted last year survived the winds and torrential rains, but they were more mature plants. So, to discover that this is a handheld anemometer requires a new plan! The equipment arrives in a convenient case, and the instructions are detailed and easy to follow. The equipment is obviously well-made and impressive. We’ll be experimenting with it this summer to find the best location to take readings. I’ll amend this review to reflect our experience.

Overall I think that this device works well and seems to be relatively accurate. I race sailboats and have for pretty much all of my life so I have a pretty good estimate of wind speeds as many of the larger boats I've raced on have anemometers on top of the mast giving a true wind speed/direction reading.The wind direction is where this falls short. I was somewhat under the impression that the head rotated on this to get the wind direction. While the product description is misleading saying it gives direction, it actually does give compass readings. The caveat being, you need to turn your arm into the direction of the wind. As the wind is not visible, it's still a best guess effort if you're facing 100% into the direction of the wind.This unit doesn't cost much more than the smaller pocket-sized units but brings far more features to the table. We'll be using this when we have to do our race committee duty during the season.

Pros: Comes in a nice plastic container to protect it. Easy to read instructions. It is accurate for both wind speed, compass and thermometer. It also tells you the intensity of the wind. We got this because we live on an island and get really bad windstorms, we thought it would be cool to read the levels of the storm and have really liked it so far. Cons: it was difficult to retract because we didn't realize we had to pull the cord down in order to retract. Also, the metal connecting the head to the extendable handle was pretty flimsy and broke pretty easily. We have hot glued it back on and it is okay now.This anemometer and thermometer is accurate and other than the one part I talked about, well put together. I still believe this is well worth the money.

I have a couple other Wintact measurement devices and have been impressed by the overall quality of them for the features and cost and so far I'm finding this anemometer doesn't break with the trend. The device itself is all plastic and not particularly special in any way in terms of sturdiness but overall feels solid enough and not outright cheap. It doesn't have a rechargeable battery and takes four AAA batteries (included), and at the end of the day I actually prefer this to a lithium battery built in when it comes to relatively infrequently used tools as this means it'll always be ready to go and work when you need it as long as you have some standard batteries around. The screen is huge and easy to read, and there is a bright backlight (you manually turn the backlight on and off by short pressing the power button). It shows a huge amount of data right on the unit all at once without having to constantly switch modes or anything.You can definitely find a basic anemometer for a lot less than this but this has a few key useful features that differentiate it. The first thing is that it also measures temperature and humidity though I have some reservations about that I'll get to. Second thing is it actually can measure wind angle. Third thing is that you can connect it to a PC and monitor in real time or analyze recorded data in the software.Temperature and humidity are "okay" in terms of accuracy. I found that the temperature generally reads about 1C higher than actual, and the humidistat measures a pretty big 15% or so higher than actual. I've compared these to the values in my house measured by my HVAC equipment at the place where it measures them, which I've previously determined are pretty much spot on. You may want to take the RH measurement of this device with a grain of salt.The wind angle works with what appears to be some kind of digital compass or gyroscope built into the hand held "fan" portion of the unit and shows in real time the angle you have it pointing (assuming you have the stick pointing straight up) in terms of degrees of rotation and it seems to be accurate and responsive out of the box.Wind speed and flow/quantity seems accurate though I have no other device to compare the measurements against. One thing that I noticed was that the CFM measurement is listed in the specs as going from 0 but there is enough resistance in the fan that measures it that I was unable to get the fan spinning to take any measurement smaller than around 40 cfm. If you need to make measurements of very small amounts of flow under about 50 cfm this may not be for you.The software is kind of clumsy and clunky, and reminds me of Windows software that might have been common in design 10-15 years ago. While it may not be pretty or particularly intuitive, it does work and will do the job. It can be used to show real time data from the device or historical stored data and does have some basic charting built in. Now the saving grace of the software even if it doesn't do everything you need for analysis is that it can export the data in standardized format for import into whatever more powerful data analysis software you're more comfortable with using.

Works great. Good tool to measure HVAC output. Recommend

This anemometer can provide me wind speed, wind direction, air tempaerature, and others. it is a very useful tool for the long range shooting (over 1000 yards).

Instrument literally worked once then started giving false readings. I checked all the operation specifications and they were not breeched yet this instrument still does not work.Disappointed.
